During a further search of the street below, the cops recovered 10 bullet fragments, including eight copper and two lead-jacketed bullet fragments that were deformed. Another bullet was embedded in the body of the van.

Investigators rounded up prisoners busted that night near the Millbrook Houses and grilled them for leads to the identity of the brazen shooter, sources said.

The reckless targeting of uniformed cops comes three weeks after Police Officer Peter Figoski was shot to death on Dec. 12, allegedly by gun-toting burglar Lamont Pride, in East New York, Brooklyn.
